Description
The EONECROSS 10×10 post base creates a sturdy connection between a large wood post and a concrete surface. Made from 2mm thick steel, this heavy-duty bracket fits wood posts with an actual size of 9.5″ x 9.5″.
The 1.2-inch ground standoff keeps the bottom of the post above the mounting surface. As a result, it helps limit direct contact with moisture and standing water. This design makes the bracket a practical choice for suitable pergolas, decks, patios, gazebos, porches, and other outdoor projects.
10×10 Post Base for Concrete
This 10×10 post base for concrete provides a practical mounting point for compatible large wood posts.
The heavy-duty steel structure connects the post to a suitable concrete surface. In addition, pre-drilled mounting holes work with the included expansion anchors and self-tapping screws.
The adjustable design also helps you position the post during installation. Once the bracket is properly installed and tightened, it helps reduce unwanted movement around the bottom of the post.
Before installation, check the condition of the concrete and confirm that the supplied hardware suits your project.
Fits 9.5″ x 9.5″ Wood Posts
A nominal 10×10 wood post commonly measures approximately 9.5″ x 9.5″ after milling.
This 10×10 wood post base is designed to fit that actual post dimension. However, lumber sizes can vary between suppliers. Therefore, measure your actual post before ordering.
The bracket works well for suitable outdoor projects that use compatible 10×10 wood posts, including:
- Pergolas
- Decks
- Patios
- Gazebos
- Porches
- Outdoor woodworking projects
For the best fit, make sure your actual post dimensions match the bracket opening. If you need a smaller post connection, see our 8×8 post base for concrete for nominal 8×8 wood posts.
Heavy-Duty 2mm Steel Construction
We use 2mm thick steel to build this 10×10 post bracket.
The heavy-duty steel construction provides a sturdy connection between the wood post and concrete mounting surface. Meanwhile, the reinforced design helps the bracket handle normal outdoor use.
This 10×10 post anchor provides a practical mounting point without placing the bottom of the wood post directly on the concrete.
For structural applications, always select appropriate lumber, anchors, fasteners, and installation methods for your specific project.
1.2-Inch Ground Standoff
The bracket raises the bottom of the wood post approximately 1.2 inch above the mounting surface.
This elevated design helps reduce direct contact between the wood and concrete. As a result, it can help limit moisture exposure around the bottom of the post.
The raised connection also provides clearance underneath the wood post. However, proper drainage and installation remain important for outdoor projects.
Silver Galvanized Finish
The 10×10 post base features a silver galvanized finish. The zinc coating helps protect the steel surface from corrosion during normal outdoor exposure while giving the bracket its silver appearance.
However, outdoor conditions vary. Regularly inspect the hardware and keep the mounting area clean and properly drained.
Adjustable Design for Easier Leveling
The adjustable design helps make post positioning easier during installation.
First, mount the bracket to the prepared concrete surface. Next, place the wood post inside the bracket. Then, adjust the connection to achieve the desired position before tightening the hardware.
This design can make it easier to fine-tune the post position during installation.
As a result, you can spend less time making small alignment adjustments.
